somehow i knew you'd bring this up gothick...
as outrageous as the plots were the series was a soap opera(read:sponsored by the manufacturers of housewife friendly products like,well,laundry detergent)and was,even in it's own time,a bit "square".
the male characters tended to be either suited up dandies(barnabas,roger)or blue collar joes(joe haskell,tom jennings).even with his muttonchops quentin was still a jacket-wearing member of an upper class family.
i think that 1970 characters like jeb and bruno were a somewhat late attempt at representing the "counterculture" percolating at the time.jeb was,if i recall,a motorcycle riding photographer.sort of a lame "easy rider" if you will.hence the long hair and shaggy coats.kind of lame but that's my impression of it.
